Description
Technical field
The present invention relates to it is a kind of for diaphragm valve, comprising the diaphragm for the ontology being made of elastomer, wherein the ontology
With the side towards medium and the side away from medium, it is used for wherein being equipped on the side away from medium on the body
By the force transmitting member fixed for the valve rod of diaphragm valve, and the ontology has enhancing region.The invention further relates to a kind of systems
The method for making this diaphragm.
Background technique
This kind of diaphragm is the standard element in diaphragm valve, and diaphragm valve is used in process technology and system engineering, is used for
Arbitrary medium is conveyed in pipeline.In general the working principle of diaphragm is always based on: the wall portion of an elastically deformable is provided,
It is for changing the through flow cross section in valve seat area.Move flexible sheet towards or away from valve seat.
20 2,014 103 142 U1 of DE disclosed a kind of diaphragm valve, and it includes the preambles with claim 1
The diaphragm of feature.In addition, the tissue layer for being internally embedded humidification of the substrate material in diaphragm.DE 2 063 509,
DE 74 20 903, DE 102 26 410 and US 2,615,471 disclosed other have be completely embedded into the elastomer
The diaphragm of enhancement layer.US 3,130,954 disclosed the film with the enhancement layer on the side towards medium for being located at elastomer
Piece.DE 20 2,009 013 401 disclosed a kind of diaphragm streamed in two sides in air reversing valve.US 6,230,
609 disclosed the elastomer diaphragm of multilayer.
Requirement to this diaphragm is heavily dependent on loading position and the application field of diaphragm valve.Usual situation
Under, the diaphragm in diaphragm valve is pressed into resting position under pre-tension.Background is, the case where power down and/or pressure supply are interrupted
Under, the switching position of valve is necessary for known.In the case where needing Vavle switching, actuator is manipulated, overcomes preload
Power simultaneously forces diaphragm to enter an alternative switching position.This is usually carried out by compressed air, magnetic coil or the like.
Handover operation occurs suddenly, and repeats depending on application example or disposably execute.
In view of this, the diaphragm of diaphragm valve has to comply with two standards: on the one hand must assure that diaphragm closing in diaphragm valve
Coincidence set in it is sufficiently sealed, this is realized by making the elastic body of diaphragm be extruded on valve seat and generate sealing surface whereby.Also
That is, diaphragm must have enough elasticity.In addition, the elasticity of diaphragm must be so high, so that being switched fast operation will not lead
Cause component failure.
On the other hand, especially for the diaphragm valve being closed in resting position, diaphragm must be subjected to lasting extruding
Stress.Must assure that will not generate plastic deformation and/or crackle in diaphragm.Also that is, ontology must have certain durability.This
Outside, in closed state, the gross pressure of medium to be intercepted always is consequently exerted on diaphragm.Diaphragm must endure as this back-pressure, and
Crackle is not formed or diaphragm deformation occurs.In general, optimization project is to improve the elasticity and durability of diaphragm.With being used as
The common diaphragm of the elastomer of ontology is not although elasticity needed for can be realized generation sealing function, has usually and resist crackle
Durability needed for being formed.
To reach this optimization project, the prior art proposes that the elastomer of diaphragm has the increasing being implemented on inside elastomer
Strong layer.This enhancement layer is for assigning diaphragm with necessary crack resistance；Elastomer makes diaphragm have elasticity.It is existing for result
Generally three layers of this kind of enhanced diaphragm disclosed in technology.
Since the enhancement layer addressed is completely in the internal stretch of elastomer, the external action face of diaphragm and the total thickness of diaphragm
Degree remains unchanged, and so there is no need to make structural modification in valve body.
For the sake of simplicity it is assumed that setting the given thickness of elastomer for diaphragm.This thickness is so chosen, so that diaphragm
With enough pliabilities, and there is enough durabilities after cooperating with enhancement layer.The case where enhancement layer is constructed in diaphragm
Under, the thickness of elastomer is constant for summation.But due to being embedded in enhancement layer, be located on the outside of elastomer with enhancement layer it
Between elastomer thickness reduce, usually halve.
Consequent is various negative effects.Defect is for example are as follows: the reduction of elastomer thickness so that valve sealing function
It is easier to be disturbed.
Enhancement layer based on the fact that usually connect by another negative effect by tackifier with elastomer.But at present
The tackifier known include at least the chemical constituent that should not be contacted with critical medium (such as food or drug).Many otherization
It learns and bioprocess also never allows to contact with the chemical constituent in tackifier.Therefore, subtract as described above in elastomer thickness
In the case where small, since the wall thickness of the elastomer layer with medium adjacent reduces, following risk increases: the chemical constituent in tackifier
Diffuse into medium across elastomer, or even due to the material damage in elastomer directly and media contact.
Generally it is ensured that the enhanced diaphragm being currently known is although with higher by enhancement layer
Intensity, but this adjoint limited working performance and huge manufacture difficulty.This is especially attributed to the triple layer designs side of diaphragm
Case.
Summary of the invention
In this context, it is an object of the invention to disclose a kind of diaphragm for diaphragm valve and a kind of manufacture film
The method of piece, wherein still improving the working performance of component although manufacturing cost reduces.
The present invention is according to diaphragm described in claim 1 and according to right to the solution for reaching above-mentioned purpose
It is required that method described in 9.Advantageous modification of the invention is refering to dependent claims.
Also that is, diaphragm of the invention is characterized in that, the enhancing region is arranged in the ontology on the outside of the ontology
On the side of medium.
" towards the side of medium " representation of concept be diaphragm a surface or outer profile, compared with diaphragm the other side,
Surface or outer profile are closer to medium to be conveyed.It is not intended that medium to be conveyed must be with the side towards medium of diaphragm
Contact.It definitely says it, middle layer or intermediate cavity can also be equipped between diaphragm and medium to be conveyed.Therefore, this concept
For opposite position description, the relationship of definition and the other side of diaphragm.Similarly, indicated " away from the side of medium " side compared with
The other side, surface or the outer profile of diaphragm are farther away from medium to be conveyed.
Enhancing region is arranged in the scheme in the outside of ontology based on the insight that enhancing usually can will be set in two sides
Elastomer layer on region is reduced to an independent layer, and the elastomer layer is whole between enhancing region and medium to be conveyed with it
A thickness works.So, in the closed state of the valve, the whole thickness of elastomer is used equally for possible out-of-flatness
Property compensates.This kind of irregularities for instance it can be possible that because material damage or deposition in surface roughness, valve seat impurity
Cause.
Another understanding is to be preferably able to carry out visual inspection to the enhancement layer.This is for example by by valve module, particularly valve casing
Assembly removal realizes, even if thus under the loading state of valve, also can to enhancing region with regard to its in diaphragm away from medium
Situation on side is inspected.Just visual inspection can be carried out to diaphragm especially during the manufacture of diaphragm, to for example know in time
It defective diaphragm and Chu not be recalled.
Further, since the second elastomer layer applied and overlayed on the side of medium is not used, " enhancing region " and " this
The contact surface of body " halves, to be substantially reduced each layer from a possibility that removing each other.
In this regard, " enhancing region " concept has referred to the layer of humidification.Its for example can be fabric backing materials,
Material or mixture.It is important that the crack resistance of the enhancement layer is higher than the ontology.
According to an advantageous modification, the enhancing region is fabric.Fabric is applied in enhancing region or is used as
The advantages of enhancing region, is the distinctive mechanical strength value of fabric.By the way that elastomer is combined with each other with the fabric for being used to enhance,
Can by any elastic body on the side for being located towards medium, and by advantageously will be located at away from medium one
Unit area stress export within the scope of fabric on side, realizes optimal valve base sealing.
In an application of the invention, the fabric constitutes a kind of sliding layer.So, longer in the downtime of diaphragm
In the case where just will not occur between force transmitting member and elastomer high level attachment because by fabric by force flow preferably
Import the elastomer of diaphragm.This facilitates the entire life for extending diaphragm.
In addition, the enhancing region being made of fabric preferably has warp thread and weft systems.Warp thread and weft systems
Advantage is to assign fabric with higher intensity and crack resistance, without causing to the flexible of fabric and other desired characteristics
Substantive negative effect.This passes through the advantageous power transmitting realization along each fiber of the fabric with warp thread and weft systems.
In general, the deciding factor of the material property in enhancing region are as follows: each fiber of enhancing region or fabric
Material composition.
In addition, the enhancing region preferably has synthetic fibers in relevant application field.In this regard, " synthesis is fine
Dimension " concept refers to such as polyester fiber, aromatic polyamide fibre, Fypro, polyamine ester fiber, polypropylene fibre, polyolefin
The plastic optical fibre of fiber or above-mentioned mixture.In general, can both use thermoplastic, can also using elastomer or
Person's thermosetting plastics.It the use of the advantages of synthetic fibers is the larger flexibility in terms of application field.It depends on the needs, such as can
It is enough to meet temperature, pressure and flexible requirement by synthetic fibers appropriate composition.
Synthetic fibers also have the advantage that phase mutual friction due to external force in composite fabric when synthetic fibers
When, only cause lesser frictional force.The switching behaviour of valve just can be realized in the case where being lost without larger starting torque and power in this way
Make.Meanwhile synthetic fibers can absorb biggish tractive force, to enhance the durability of diaphragm.
In the material property to enhancing region there are also in the case where requirements at the higher level, this enhancing region can have glass fibers
Dimension enhancing or carbon fibre reinforced plastic.This is indicated, for example additional glass is added in plastics existing for matrix or fibers form
Glass fiber and/or carbon fiber.These fibers assign the enhancement layer with additional mechanical strength and temperature tolerance.
As improvement project, the enhancing region is preferably enhanced film.It is can have using the advantages of enhanced film
There is the material property of wide scope, and acquisition cost is cheap.This kind of enhanced film is preferably made of plastics or rubber, thus easily
It realizes processing and connect enhancement layer with elastomer layer in ground.In this regard, " enhanced film " concept generally refers to elastic to become
The layer of shape.This enhanced film can both be constituted by organic material or by inorganic material.Such as it can also use relatively thin
Metal layer.Wherein, the enhanced film need not have closing face formula surface and be made of an independent coherent structure.It is described
Enhanced film can also be made of several organic and/or inorganic minor structure, these minor structures co-operatively form enhanced film.
The fundamental region is preferably at least locally thicker than the enhancing region.As it was noted above, the thickness in elastomer is most
In the case that possibility is big, help to generate sealing surface as big as possible on valve seat in the closed state of the valve, and then to defeated
It send and material barrier as big as possible is provided between medium and tackifier.Therefore, the enhancement layer preferably uses as flat as possible
Design scheme, so that the overall thickness of diaphragm of the invention is identical as the overall thickness of not enhanced diaphragm.Especially require emphasis
It is thickness of the ontology in valve seat area, because of the sealing addressed above at this to valve seat.
As improvement project, composition and the effect of the ontology in the force transmitting member and/or the enhancing region
On the surface faced, tackifier are preferably provided between the acting surface.In addition to the enhancement layer, other assemblies, especially
Force transmitting member also with the film contact.It is all to be connect with ontology in order to realize the efficient attachment of all components on the body
Acting surface preferably all have tackifier.The removing risk for the component that these connect with ontology just can be reduced in this way.In this regard,
" tackifier " concept refers to the material for being suitable for that ontology being connected with adjacent component in such a way that compression fit and/or material engage
Material.
In order to extend the service life of the diaphragm, the ontology and/or the enhancing region preferably have vulcanizable elasticity
Body.The material property for improving the component based on rubber by the degree of cross linking increased in sulfidation, to enhance dimensionally stable
Property, crack resistance and the tolerance to aging and weather.The ontology can also reside in the advantages of cure, can by rubber with
Metal assembly connection.This, by the tackifier realization addressed above, is rubber to metal adhesive in this case.
As improvement project, bulk sulfided the force transmitting member and/or the enhancing region preferably are bonded to for described.
By this method can by with different shape and geometry metalwork and rubber parts be connected to and have higher removing strong
The unit of degree and corrosion resistance.This for example can be used for following scenario described: the force transmitting member needs the length stretched out along it from diaphragm
Degree is encapsulated by vulcanizable elastomer portion.Based on this encapsulating, it is capable of increasing and is available for from force transmitting member to elasticity
The significant surface of the power transmitting of body, and reduce the risk to form crackle in metal-elastomer transition position.
As improvement project, the ontology is generated by calendering preferably before vulcanization.Being capable of providing by calendering has perseverance
The initial layers of given layer thickness are used to generate the blank of the ontology for the diaphragm.Institute can also be pointedly influenced by calendering
State the surface state of ontology.It for example can be realized set roughness by calendering, or realize the texture on surface.So just
Optimal surface can be provided for subsequent vulcanisation step.It can also be according to requiring pair on the side towards medium of the ontology
Rolled on surface.Such as in the case where medium is directly adjacent with ontology, the surface can be surface as smooth as possible.
And if on the side towards medium be equipped with it is another apply the layer covered to subsequent, the roughness that preferably can slightly increase is to correlation
Rolled on surface.
Furthermore it is preferred that before vulcanization in shaping jig to the force transmitting member, the enhancing region, the ontology with
And additional elastomer is positioned.The advantage is that being positioned in shaping jig by before vulcanization, can be realized to diaphragm
The accurate positioning of all components, and it is then in an independent processing step that these components are co-vulcanized.Another advantage exists
In even if diaphragm is also able to achieve simple and repeatable manufacture using complicated design scheme.
